1" synergy front springs pic

So that picture is 1" Synergy front springs and stock rear springs with a stock Rubicon steel front bumper?

My OVERLAND result with Synergy springs:

Stock as measured hub center to the fender flare trim edge - 21.5"
I measured multiple Overland Gladiators in dealer lots - all the same.

After adding steel bumper (with skid plate), winch and 2" front receiver it dropped to 20.75

After installing Synergy 1" springs -
LF - 22
RF - 22.125
Front settled to:
Left front - 21.5"
Right front - 21.5"

So it put it back to stock height, basically, but with all of the added weight.

Having a snow plow, that just wasn't enough - it settled with the snow plow so I put Synergy 2" springs in the front -
after replacing Synergy 1" springs with 2" springs -
LF - 23.25
RF - 23.25

I have since added the RSE power steps at approximately 70 pounds per side, but those are centered between the axles for the most part. And the front springs have settled, and now it sits at 22.5 (22 1/2")

So, my truck currently sits at 1" over stock height, after the springs settled, and with the weight of a steel bumper, winch, winch plate and 2" receiver up front (and power steps on the side) with the 2" Synergy springs under it.
The 1" would likely sit at stock height, with the weight I have added to my Overland.

So - when Synergy says their 1" springs will lift a Wrangler Rubicon, with steel bumper, 1" - that could be, but it wouldn't lift a loaded Gladiator 1"

For reference - immediately after installing the 2" springs (swapping out the 1" springs) -
Front after replacing Synergy 1" springs with 2" springs -
LF - 23.25
RF - 23.25

That means with the addition of the power steps, and after settling, they have lost 3/4"
Even the 1" springs settled some after a while.

When you went from 1" to 2" spring what else did you have to do? Still using stock end links or naaah?
Very good information post, ty

I put in the lower control arms - same as used in their lift kit, which are 1/4" longer before I did anything else. I installed those with the 1" springs.
Because the 2" springs really didn't lift my JT much, I didn't do anything else.
With the added weight, and settling with time, the 2" springs netted me a 1" lift up front.

On a stock Overland I suspect the 1" springs would have been enough for me.
But the weight of the bumper, receiver, power steps, winch - it all added up.

I am very happy with the firmness of the synergy springs.
1" did me right , higher speed driving and no nose dive on harder braking.
More truck like , not "74" Bonneville floating.
I went with Fox 2.0 suggested by Dave at polyperformance. 2"-3" lift shaft length also per his suggestion.
Sits perfect too, rake is less noticeable almost have to look twice to see it.
I will try once again to post a pic for you but for 2 days nothing has uploaded for me.
Hold on ...

Did either of you install the bump stop extension?

i didn't - should I have? Probably - I "might" run into coil bind if I hammer on it hard enough, come down hard with it, but so far, so good.

That's great to hear. I'm currently running into coil bind on Rubicon springs .
